In the past few years, metal halide perovskites-based QDs have been shown to exhibit slow hot-carrier cooling characteristics that are desirable for photo-energy harvesting technologies. While several mechanisms are proposed to rationalize the retardation of the cooling dynamics, including hot-phonon bottleneck and polaronic effects, the role of inter-particle connectivity in these dynamics is largely ignored. Here, an in-depth study of photo-excitation dynamics and carrier cooling on perovskite QD solids with varying degrees of inter-dot coupling is presented. It is observed that inter-particle connectivity has deterministic effects on the many-body interactions that are relevant for carrier cooling. These include carrier–carrier interactions that result in Auger-reheating of the carriers, and lattice characteristics that subsequently affect the phonon-assisted cooling dynamics. This spectroscopic study of ultrafast carrier dynamics in perovskite QD solids establishes inter-dot separation as a critical material design parameter for the optimization of photo-generated carrier temperature, which fundamentally determines the luminescence characteristics and thus the opto-electronic quality of the material.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 31","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202401483","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, precise regulation of the structure for property enrichment is still a great challenge. Herein, the first case of a single-molecule switch BN-S with multiple structurally tunable and full-color fluorescent properties is reported. Interestingly, BN-S exhibits a butterfly-like “metamorphosis” crystal growth process accompanied by full-color fluorescence emission (including white light, CIE = 0.33, 0.33; 456 nm → 610 nm). It is shown that this is related to the reversible B←N bonding and the tunability of the spatial structure of the BN-S. Thus, BN-S exhibits superior multicolor tunability in different states (solid, liquid, and film), and its applications in white-light optical light emitting diodes (OLEDs) and multicolor fluorescent inks also show great promise. This will provide a new strategy for designing and synthesizing the development of multifunctional molecular switching materials and enriching the variety of organoboron luminescent materials.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 31","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this approach has been mainly demonstrated with red and green emitting g-QDs but the blue-emitting graded alloy QDs has remained less explored. To tackle this challenge, a composition gradient method is employed to create three blue-emitting CdZnS/CdxZn1–xS/ZnS core/interface graded alloy shell/shell (C/A/S) quantum dots (QDs) with different diameters. The sample with the largest diameter (gQD-3) exhibits superior optical characteristics, with a photoluminescence quantum yield (PLQY) of approximately 62% and around 80% ON/radiative events at the single-particle level. Conversely, the smallest diameter (gQD-1) sample shows lower PLQY and only 30% radiative events with longer OFF/nonradiative events. Probability distribution analysis of PL trajectories, fitted with a truncated power law, reveals a significantly higher carrier de-trapping rate in gQD-3 compared to gQD-1, attributed to its proximity to band edge trap states. Additionally, the largest diameter sample retains remarkable optical performance during 48 h of continuous UV irradiation in colloidal suspension and single-particle levels. These findings show optimized core/shell structures, gradual alloy interfaces, and outer shell coatings can stabilize blue-emitting quantum dots, advancing next-gen optoelectronics.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 30","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142525423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, the pressure-tunable photovoltaic properties in the SbI3 device with Au/Pt asymmetric electrodes are demonstrated. At initial pressure, the SbI3 device exhibits an anticipated self-driven photoresponse characteristic at zero external bias, and a significant enhancement in photocurrent response is observed with increasing bias to −0.2 V, nearly two orders of magnitude higher than the initial value. With increasing pressure, the SbI3 device exhibits tunable photocurrent response, reaching a maximum value at ≈1.2 GPa, while the photovoltage response decreases monotonously during compression, which is closely associated with the dynamic evolution of the work function and bandgap of SbI3 upon successive compression. These findings signify that SbI3 is a promising candidate for future photoelectric devices, which opens a new window of opportunity for further exploration, regulation, and understanding of high-performance photovoltaic devices under extreme conditions.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 31","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142588227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ion-solid interactions produce donor-like defects that boost electron concentrations from the practical minimum of 2.5 × 1019 cm−3 to a maximum of 2.5 × 1020 cm−3 by metered ion exposure. This range is achieved using He, N, Ar, or Au ions at 1–2.8 MeV; when normalized by displacements per atom, all ion species produce comparable results. Since CdO is well-described by the Drude model, irradiation-tuned carrier densities directly alter the infrared dielectric function, and in turn, mid-infrared optical properties. Further, it is demonstrated that by combining irradiation with traditional lithography, CdO films expose to ions in the presence of 3-µm thick, patterned photoresist exhibit lateral carrier density profiles with ≈400-nm resolution. Scanning near-field optical microscopy reveals sharp optical interfaces with almost no companion contrast in surface morphology, microstructure, or crystallinity. Finally, CdO lateral homostructures supporting surface plasmon polaritons (SPPs) are demonstrated whose dispersion relation can be tuned through periodic patterning in a monolithic platform by simple nanofabrication. Numerical simulations show these polaritons result from strong coupling between excitations at CdO plasma frequencies and SPPs supported by the platinum substrate.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 30","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202401009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142525230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A new mechanism of photoconversion is recently established, called Directed Photooxidation Induced Conversion based on the coupling of fluorophores with Aromatic Singlet oxygen Reactive Moieties (ASORMs). In this work, The Directed Photooxidation Induced Conversion (DPIC) mechanism is intended to be applied to Perylene BisImide (PBI) due to its appealing photophysical properties. The experimental results showed that coupling two ASORMs to the PBI core, here furan and pyrrole, led to impressive photomodulable fluorophores. While PBI-F exhibited a photoconversion of 100 nm shift, PBI-P displayed an 80-fold fluorescence intensity enhancement upon photoactivation. Analysis of the photoproducts showed that the conversion do not involve an addition of singlet oxygen on the ASORM. Instead, photoconversion occurred through efficient successive photocyclizations. Finally, intracellular vesicles are successfully photoconverted by means of endocytosed PLGA-polymer nanoparticles loaded with PBI-F. This study highlights the unique capability of furan- and pyrrole-conjugated fluorophores to enable advanced optical materials with phototransformation properties.","PeriodicalId":116,"journal":{"name":"Advanced Optical Materials","volume":"12 32","pages":""},"PeriodicalIF":8.0,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adom.202401511","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142642360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
